ELIA. MILLER, vCONNEAU'I, AND WILLIAM H. BROVN, OF NORTH KINGSVILLE, OHIO.

PUMP.

SPECIFICATION forming part of Letters Patent: No. 324,401, dated August 18, 1885. Application filed February 5, 1885. (No model.)

To all whom, it 17mg concern.-

Be it known that we, ELI A. MILLER and WILLIAM H. BROWN, citizens of the United States, residing, respectively, at Conneaut and North Kingsville, lin the county of Ashtabula and State of Ohio, have inventedl certain new and useful Improvements in Pumps; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had tothe accompanying drawings, and to the letters and figures of ret'- erence marked thereon, which form a part of this specification.

This invention relates to pumps, and has for its object to provide improvements on the pump patented to Eli A. Miller, .I une 17, 188i, No. 300,623.

The present invention consists in certain novel features of construction, as willbe here-v inafter more fully described and claimed.

Referring to the drawings, Figure 1 is a vertical section of the well with the pump, &c., in place; Fig. 2 is a detail face view of the check-valve. Fig. 3 is a vertical section of the air-cylinder. Fig. 4 is a transverse section of same. Fig. 5 shows the air-cylinder in perspective. Fig. 6 is a detached section' of the piston.

As inthe former patent, the air-cylinder A is arranged alongside the pump, which latter may be of any suitable form or desired varietyas lift, force, Sto. We preferably provide the cylinder A with plates A', to facilitate its application to the pump-stock.

The cylinder A has an opening, B, through its bottom, which is controlled bya valve, B, as will be understood from Figs.3 and 4, which will admit air on the upstroke of the piston and close the opening B in the downstroke thereof.

The piston C has its rod C carried up and connected with the handle D of the pump D, so as to be operated simultaneously with the operation of the pump. We prefer to make piston C of elastic packing-rings E, held between metallic disks E, which latter are clamped against ring E, one above and the other below, by nuts E2 E2, turned on threads formed on the piston-rod C. By tightening one or the other of the nuts L2 the packing-ring may be expanded to take up Wear.

By reason of the swing of the pump-handle D the piston-rod is not moved in a true line up and down, but oscillates slightly. This requires that the hole F' through the top F of the cylinder be made larger than the pistonrod, to permit the oscillation thereof before described. This forms an enlarged opening,

through which dust and dirt may pass.

To prevent the ingress of dust or dirt we place on the piston-rod a disk, G, which rests down on top F, and is made large enough to cover the hole F', no matter at what point of oscillation the piston-rod may be. This disk or plate G lits closely on the piston-rod, and is made of sufficient specificgravity to hold it down on the top F, on which it slides with the oscillations of the piston-rod; or it may be held in suitable guides on said top, as will be understood.

The port B is the inlet-port. The outletport H is form-ed laterally through the cylinder, near its bottom, and communicates with the connection H', being suitably controlled by the check-valve I. This valve lis preferably formed of a disk ot' leather, rubber, or other pliable material,havi ng its outer edges clamped betweeny the connection H and the cylinder. The central portion of this disk which fits over the port His imperforate, and it` is provided, without the area of said port H, with perforations I. The valve I, it will'be seen, is formed with an outer ring, an inner imperforate portion or disk, and strips t', connecting the said ring and central portion or disk. On the upstroke of the piston the valve I is drawn closely against and closes( port H. On the downstroke of the piston the valve is forced out away from port H, and the air passes off through openings l, as will be understood.

The pipe J is connected at its upper end by L H with the air-cylinder, and depends thence into the well.

A suitable air-discharge,K, is formed through the curbing, so as t'o permit the proper circulation of air out of the well as fresh air is forced thereiuto by the air-pump.

In the former patent, above referred to, we

IOO

have described the'advantages attending the forcing` ofair into the well. In addition thereto we have found it desirable to force the air directly into the water, as by so doing the water becomes aerated and more palatable. In carrying out this project, experience has demonstrated that when the pipe projects straight down into the water and is Open at its lower end the air forced therethrough into the water produces a current of water, which7 stri king the bottom ofthe Well, stirs up the accumulated sediment and mud, rendering the water thick and undesirable for use. To obviate this objection we turn the lower or discharge end J of the air-pipe so that it will not direct the air toward the bottoni. This turning may be only at a right angle; but in such case a current would be directed against the side of the well, which, in sonic cases, is also full of sedi1nent,which will be stirred up by the current of water. Ve prefer, therefore7 to turn the end of the pipe so that its open end will project upward, thus directing` all currents produced by theair-diseharge directly up toward the surface oi' the water. rlhis arrangement, it will be seen7 will not produce any currents lik ely to disturb the sedi ment, mud, ttc., and yet accomplishes the desired end inan efiieient manner.

It is manifest that the upturned end of the airdiseharge pipe would give goed results in an open well without a pump; but we prefer to use it in connection with a pump, as thereby the simultaneous operation of the air and water pump is secured, and the air-pump is certain to be properly and sufficiently worked to give the desired results.

Having thus described our invention, what we claim7 and desire to secure by Letters Patent, is-

The device hercinhefore described for aerating water in wells, consisting of au air-pump and a discharge tube extended downward from the air-cylinder, and adapted to enter the water in the well, and having its lower end turned upward, substantially as and for the purposes set forth.

ln testimony whereof we affix our signatures in presence oi two witnesses.
